Ryan Naraine talks to Vupen CEO Chaouki Bekrar about the controversies surrounding the sale of zero-day vulnerabilities and exploits, his company’s business dealings and the work that goes into winning the CanSecWest Pwn2Own hacker contest. This interview was done just moments after Bekrar's research team demonstrated a zero-day attack against Microsoft Internet Explorer 10 on Windows 8, an exploit that bypassed all mitigations including the browser sandbox.
